Rapid7 Threat Command CVEs Correlation

This rule is triggered when CVEs collected from the Rapid7 Threat Command Integration have a match against vulnerabilities that were found in the customer environment.

Windows CryptoAPI Spoofing Vulnerability (CVE-2020-0601 - CurveBall)

A spoofing vulnerability exists in the way Windows CryptoAPI (Crypt32.dll) validates Elliptic Curve Cryptography (ECC) certificates. An attacker could exploit the vulnerability by using a spoofed code-signing certificate to sign a malicious executable, making it appear the file was from a trusted, legitimate source.

Cassandra JavaScript UDF Creation

Identifies Cassandra Query Language statements that create a JavaScript user-defined function. On vulnerable and dangerously configured Cassandra servers, adversaries can abuse scripted UDF creation to escape the JavaScript sandbox and execute operating-system commands, including through CVE-2021-44521.

Deprecated - Suspicious JAVA Child Process

Identifies suspicious child processes of the Java interpreter process. This may indicate an attempt to execute a malicious JAR file or an exploitation attempt via a JAVA specific vulnerability.

Suspicious Print Spooler SPL File Created

Detects attempts to exploit privilege escalation vulnerabilities related to the Print Spooler service including CVE-2020-1048 and CVE-2020-1337.

Deprecated - Sudo Heap-Based Buffer Overflow Attempt

Identifies the attempted use of a heap-based buffer overflow vulnerability for the Sudo binary in Unix-like systems (CVE-2021-3156). Successful exploitation allows an unprivileged user to escalate to the root user.

Potential SAP NetWeaver Exploitation

Identifies suspicious processes spawned from the SAP NetWeaver application. This may indicate an attempt to execute commands via webshell.

Telnet Authentication Bypass via User Environment Variable

Identifies potential exploitation of a Telnet remote authentication bypass vulnerability (CVE-2026-24061) in GNU Inetutils telnetd. The vulnerability allows unauthenticated access by supplying a crafted `-f <username>` value via the `USER` environment variable, resulting in a login process spawned with elevated privileges.

Potential Privilege Escalation via CVE-2023-4911

This rule detects potential privilege escalation attempts through Looney Tunables (CVE-2023-4911). Looney Tunables is a buffer overflow vulnerability in GNU C Library's dynamic loader's processing of the GLIBC_TUNABLES environment variable.

Abnormally Large DNS Response

Specially crafted DNS requests can manipulate a known overflow vulnerability in some Windows DNS servers, resulting in Remote Code Execution (RCE) or a Denial of Service (DoS) from crashing the service.

Potential Privilege Escalation via InstallerFileTakeOver

Identifies a potential exploitation of InstallerTakeOver (CVE-2021-41379) default PoC execution. Successful exploitation allows an unprivileged user to escalate privileges to SYSTEM.

Suspicious Command Execution via Web Server

Identifies suspicious command executions via a web server, which may suggest a vulnerability and remote shell access. Attackers may exploit a vulnerability in a web application to execute commands via a web server, or place a backdoor file that can be abused to gain code execution as a mechanism for persistence.

Potential SAP NetWeaver WebShell Creation

Identifies suspicious Java file creation in the IRJ directory of the SAP NetWeaver application. This may indicate an attempt to deploy a webshell.

Suspicious Child Execution via Web Server

Identifies suspicious child processes executed via a web server, which may suggest a vulnerability and remote shell access. Attackers may exploit a vulnerability in a web application to execute commands via a web server, or place a backdoor file that can be abused to gain code execution as a mechanism for persistence.

Suspicious JetBrains TeamCity Child Process

Identifies suspicious processes being spawned by the JetBrain TeamCity process. This activity could be related to JetBrains remote code execution vulnerabilities.

Suspicious Print Spooler File Deletion

Detects deletion of print driver files by an unusual process. This may indicate a clean up attempt post successful privilege escalation via Print Spooler service related vulnerabilities.

Potential Privileged Escalation via SamAccountName Spoofing

Identifies a suspicious computer account name rename event, which may indicate an attempt to exploit CVE-2021-42278 to elevate privileges from a standard domain user to a user with domain admin privileges. CVE-2021-42278 is a security vulnerability that allows potential attackers to impersonate a domain controller via samAccountName attribute spoofing.

Potential Telnet Authentication Bypass (CVE-2026-24061)

Identifies potential exploitation of a Telnet remote authentication bypass vulnerability (CVE-2026-24061) in GNU Inetutils telnetd. The vulnerability allows unauthenticated access by supplying a crafted `-f <username>` value via the `USER` environment variable, resulting in a login process spawned with elevated privileges.

Deprecated - Potential curl CVE-2023-38545 Exploitation

Detects potential exploitation of curl CVE-2023-38545 by monitoring for vulnerable command line arguments in conjunction with an unusual command line length. A flaw in curl version <= 8.3 makes curl vulnerable to a heap based buffer overflow during the SOCKS5 proxy handshake. Upgrade to curl version >= 8.4 to patch this vulnerability. This exploit can be executed with and without the use of environment variables. For increased visibility, enable the collection of http_proxy, HTTPS_PROXY and ALL_

Suspicious Child Process of Adobe Acrobat Reader Update Service

Detects attempts to exploit privilege escalation vulnerabilities related to the Adobe Acrobat Reader PrivilegedHelperTool responsible for installing updates. For more information, refer to CVE-2020-9615, CVE-2020-9614 and CVE-2020-9613 and verify that the impacted system is patched.

Potential Redis Lua Use-After-Free RCE Attempt (CVE-2025-49844 / RediShell)

This rule detects exploitation attempts targeting CVE-2025-49844 (RediShell), a CVSS 10.0 use-after-free vulnerability in the Redis Lua interpreter. An authenticated attacker sends an EVAL command containing a Lua script that calls string.rep() to create memory pressure and collectgarbage('collect') to force garbage collection, exploiting a use-after-free in the Lua parser to achieve remote code execution.

Multiple Vulnerabilities by Asset via Wiz

This alert identifies assets with an elevated number of vulnerabilities reported by Wiz, potentially indicating weak security posture, missed patching, or active exposure. The rule highlights assets with a high volume of distinct vulnerabilities, the presence of exploitable vulnerabilities, or a combination of multiple severities, helping prioritize assets that pose increased risk.

Unusual Print Spooler Child Process

Detects unusual Print Spooler service (spoolsv.exe) child processes. This may indicate an attempt to exploit privilege escalation vulnerabilities related to the Printing Service on Windows.

Suspicious Print Spooler Point and Print DLL

Detects attempts to exploit a privilege escalation vulnerability (CVE-2020-1030) related to the print spooler service. Exploitation involves chaining multiple primitives to load an arbitrary DLL into the print spooler process running as SYSTEM.
